`To all whom it may concern:

Be it known that I, HIRAM JOSEPH HALLE, a citizen of the United States,residing at Cleveland, in the county of Cuyahoga and State of Ohio, haveinvented a new and useful Type -Writing Machine, of which the fol-`lowing `is a specication.

`'This invention relates to type-writing machines, and has specialreference to an illurnnating attachment designed to illuminate thework-sheet for the purpose of facilitating i the inspection of the work.

It frequently happens, particularly in large establishments, thattype-writing machines are locatedat points whereitis impossible tosecure sufficient light; and my invention therefore has for its objectto provide the 4machine with an electric light, so located that the workwill be illuminated either continuously or intermittently, according tothe.

desire ofthe individual operator.. Y

` To the accomplishment of this objectthe invention comprehends theattachment of a small electric light at a convenient point upon theframestructure and in the provision of circuit-'closing devices arranged topermit the circuit to be closed through the lamp continuously if aconstant light 'is desired or intermittently if it is desired toilluminate the Work at intervals only-as,

printing-point to reveal the writing.

Certain other objects subordinate to those enumerated and various novelfeaturesof lconstruction and arrangement will appear during the courseof the following description of that form` of my invention which for thepurpose of this disclosure is illustrated in the accompanying drawingsand succinctly deined in the appended claims.

In said drawings, Figure; l is a perspective `view of a Fishertype-writing machine equipped-.with mylightingattachment. Fig. 2`is asectional elevation iof the same. Fig. `3 is a bottom plan'view, partlyin section, of a portion of the traveling carriage, illustrating themanner in which the attachment is mounted thereon. Fig. 4 is a detailview of the lamp and its bracket. Fig. 5 is a detail for instance, atSuch times as the ribbon may be shifted lat` erally from the perspectiveView of the contact-armcarried by the lamp, and Fig. 6 is a similar Viewof the movable contact-arm and the bracket for securing thesame to theribbon-shift shaft.

Like characters of reference are employed to designate correspondingparts throughout the views.

Vhile the invention broad aspect the equipment of a type-writing machineof any characterwitha lighting or illuminating device, the attachmentillustrated in the accompanying drawings is particularly designed forthe equipment of what is known in the art as a Fisher7type-writcontemplates in its "ing machine, to which it is shown applied.

The Fisher type-writer includes iu its organization what is known as themachine-frame 1, designed `to travel longitudinally over the flat platen(not illustrated) and slidably supporting a carriage 2, movabletransversely of the platen. This carriage supports the printingmechanism, including the keys 3, operatively connected to a series oftype-bars 4, mounted upon a supporting-ringofsegmental form sustained atthe lower ends of vertical bars or hangers, twoof which (indicated by 6and 7) are pendent fromthe carriage proper adjacent to its front edge,as indicated in Fig. l. Thesebars or hangers 6 and7 are located at theends of the segmental type-bar-supporting ring 5, and as the type-barsstrike downwardly toward the axis of the type-ring the printing-point isin full view of the operator. During the printing operation, however,the line being Written is obscured by the ribbon 8, which extends underthe typering from the opposite sides of the carriage, where its ends arewound upon the ribbonspools 9 and 10, shiftably mounted upon thespool-shafts 11, journaled in shaft-hangers 12, as shown. The ribbon isfed longitudinally, in a manner well understood in the art, by therotation of the ribbon-spools; but as the ribbon-feeding mechanismconstitutes no part of the present invention ithas not been fullyillustrated and Aneed not be described.` f

In the present embodiment of the invention provision has been madeforclosing the circuit through an electric lamp, constitut- ICO ing theprimary element of the attachment, Whenever the ribbon is shiftedlaterally to expose the writing,and the ribbon-shift mechanism, althoughno part of my present in-v vention, except as it enters into a novelcombination, may therefore be described. Associated with each of theribbon-spools so`- as to be shiftable therewith areribbon-framesupporting brackets 13, connected to a ribbon guiding andsupporting frame 14, designed to properly guide the ribbon as it is fedfrom one spool to another and to maintain the ribbon in proper positionas it is shifted laterally. The ribbon-shift mechanism-that is to say,the mechanism by means of which the operator shifts the ribbon laterallyfrom the printing-pointwhen it is desired to inspect the writingincludesa ribbon-shift key 15, formed at one end of a ribbon-shift lever 16,secured to the end of a rock-shaft 17 and having its lower extremityforked, as indicated at 18, for engagement with a stud 19, projectingfrom the adjacent bracket 13. Ordinarily the ribbon occupies a positionopposite the printing-point and is yeldingly retained in such positionby a spring I2O, coiled upon the shaft 17 and having its opposite endsengagedv by a set-collar 21, secured to the shaft, and a post 22,secured to the bottom of the carriage-casing. (See Figs. 2 vand 3.) Itwill be noted that upon the depression of the ribbon-shift key 15 theribbon, together with its frame and spools, will be laterally shifted asufficient distance to entirely displace the ribbon from theprinting-point, and as the front of the carriage is open (see Fig. l)this lshifting of the ribbon will reveal the writing for the inspectionof the operator. Upon the release ofthe key the spring 20 willautomatically return the ribbon to its initial position.

The structure embraced in the foregoing description is all that need bedescribed in order that the relation of the lighting attachment to themachine may be fully comprehended, and the construction and arrangementof the attachment proper will now be considered.

The lamp (indicated by 23) is preferably whatis known as an incandescentelectric lamp of small size and is located in the present instance immediatel y below the carriagecasing, adjacent to the front edge thereof,and directly above the printing-point. This location of thelamp isdesirable for the reason that while it' enables the writing to beproperly illuminated the lamp is more lor less obscured from theoperator by the carriage. The lamp 23 is retained, as usual, by a lampholder or socket 2 4, to which latter I have attached a lamp-bracket 25.This bracket is bifurcated for the reception of the hanger or uprightbar 7, adjacent to the upper end of which it is secured. It will ofcourse be understood that the particular manner of attaching the lamp tothe machine structure may be varied as occasion may require; but in theillustrated structure the bifurcations 26 and 27 of the bracket 25 areextended somewhat beyond the hanger 7 for the reception of a draw-bolt28,

by means of which the bifurcations are drawn up to securely clamp thelamp-bracket to the hanger. It will be noted that by locating the lampas stated it will be disposed closely adjacent to and parallel with theribbon-shift shaft 17. This is particularly desirable for thereason thata circuit-closing device for the lamp-circuit may thus be operated bythe movement of the shaft to close the circuit through the lamp wheneverthe ribbon-shift mechanism is operated to move the ribbon away from theprinting-point.

To one terminal plate 29 of the lamp is adjustably attached, by means ofa screw 30, an angular contact-arm 31, one end 32 of which extendshorizontally and has an upturned or deflected end 33 located adjacent tothe ribbon-shift shaft 17. (See Figs. 2 and 3.) A second contact-arm 34is adjustably secured to the ribbon-shift shaft 17-as, for instance, bymeans of an attaching-bracket 35,'secured inplace by a draw-bolt 36. Thearm 34 is disposed substantially parallel with the shaft, slightly toone side thereof, and is designed to contact with the end 33 of thecontact-arm 31 when the ribbon-shift shaft 17 is rocked by thedepression ofthe ribbon-shift key 15 when the ribbon is shiftedlaterally to expose the Writing. These contact-arms '3l and 34constitute a circuit-closing device for the lamp. y

A lead-wire a is connected to the contactarm 34 (see Fig. 3) and to abinding-post 37, mounted on a switch-block 38, preferably mounted uponone end of the carriage-casing adjacent toits rear edge. Asecondlead-wire b is connected to the second terminal plate 39 of the lamp andto a second binding-post 40 on the switch-block, circuit-wires a: and ybeing extended from the binding-posts to a suitable source of electricalenergy. In the accompanying drawings I have indicated a battery B in thelamp-circuit; but obviously the circuit-wires of the lighting and powersystems installed intbuildings might be attached to the binding-postswith equal facility.

ICO

IIO

It will now be observed that whenever the the ribbon will be shiftedaway from the print- 1 ing-point, and vthe shaft 17 will be rocked forthe purpose of closing the lamp-circuit by bringing the arm 34 intocontact with the arm 31, and the lamp will thus be automatically lightedwhenever the ribbon-shift mechanism is operated. The lamp-circuit whenclosed in the manner stated may be traced 'as follows: from thebinding-post 37 through the wire a to the contact-arm 34, thence to thearm 31, to the lamp-terminal 29, through the lamp to the terminal 39,through the wire b to the binding-post 40, and thence through thecircuit-wires and battery to the firstnamed binding-post 37. Upon therelease of the ribbon-shift key the ribbon will be re- 35 i ing-post 37,upon which is mounted aswingstored to its normal position by the spring20, and the shaft 17, beingrocked in the reverse direction, willmove thecontact-arm 34 away from the arm 3l to break-thc lamp-circuit, and thusautomatically extinguish the light after the illuminated work has beeninspected.

The arrangement described is considered `preferable when the attachmentis employed in connection with a Fisher` type-writing machine; but it isby no means essential that the ribbon-shift mechanism be utilized forthe purpose of effecting the opening and clos-` ing of the lamp-circuit;The desired end may `be attained byarranging a circuit-closingdeattachment merely as a device for illuminating the writing Wheneverthe latter is exposed by the shifting of the ribbon; but'it may bedesirable under some circumstances to employ the light continuously, andthis may be done Without annoyance to the operator, for

the reasouthat the lamp is so located, as heretofore stated, that theeyes of the operator will be shielded from the bright light. I

have therefore connected a third lead-wire c 'to the contact-arm 31 andto a contact-plate 41, mounted in the switch-block 38. The contact-plate41 is located to one side of the binding switch-arm 42, designed to beswung into and out of contact with the plate 41. If the operator desiresa constant light, it is simply necessary to swing the switch-arm 42 intocontact with the plate 41, thus closing the circuit through the lamp asfollows: from the binding-post 37 through the arm 42, contactplate 41,Wire c, arm 3l,.lampterminal 29,

`45 thence through the lamp to the terminal 39, thence through the WireZJ to the binding-post` 40,"and thence through the circuit-wires andbattery back to the binding-post 37.

j From the foregoing my lighting attachment will be seen to include anelectric lamp carried by the machine structure and a pair ofcircuit-closing devices, one of which is rnanually operated for 4thepurpose of securing a Vcontinuous or constantlight and the other ofwhichis automatically operated `intermittently by a moving part of themachine, preferably an element of the' ribbon-shift mechanism, to effectthe lighting of the lamp at l such times only as the Writing may berevealed to the operator by the shifting of the ribbon away from theprinting-point. I Wish it to be distinctly understood, however, thatWhile the present embodiment of the invention is thought at this time tobe preferable the invention in its broader aspect comprehendstheequipment of a type-Writing machine with an electric light or otherilluminating device, irrespective of its construction and arrangement,and I therefore reserve the right to effect such changes, modifications,and variations of the illustrated structure as may be fairlycomprehended within the scope of the protection prayed. For instance, ifapplied to cylindrical-platen machines the lamp should be attached to afixed part of the frame at a suitable point to throw light on the workand in such relation to the carriage that when the same is raised toview the work the light is turned on by the mere act of raising thecarriage, and I desire it understood that I consider this modificationto come within the purview of my invention.
